代号一本机地图未显示 [英] Codename one Native Map not showing
问题描述
我正在为项目使用本机地图CN1Lib。我遵循了此处的说明>，并添加了所需的构建提示。在模拟器中，地图看起来不错，但是当我将其导出到android（在android studio上调试）时，地图仅显示为灰色矩形，左下角带有 Google。
I'm using the native map CN1Lib for my project. I followed the instructions from here and added the required build hints. In simulator the map looks fine but when I export it to android (debug on android studio), the map only shows as a gray rectangle with "Google" on the left bottom.
我认为这是有关google api的问题，因此我在google控制台上创建了一些新的api密钥。所有键均不受限制。 Google Maps Android API也已启用，但问题仍然存在。我还检查了导出的apk中的AndroidManifest.xml中是否包含正确的api。
I thought it was a problem about google api so I created a few new api keys at google console. All keys were not limited. Google Maps Android API was also enabled, but the problem persists. I've also checked that in the AndroidManifest.xml in the exported apk the correct api is contained.
以下是构建提示（经过审查的api密钥的一部分）：
Below are the build hints (part of api key censored):
codename1.android.keystore=
codename1.android.keystoreAlias=
codename1.android.keystorePassword=
codename1.arg.android.playService.maps=true

codename1.secondaryTitle=Medi

我不确定现在如何进行。请指教。
I'm not sure how to proceed now. Please advice.

我不确定缺失的类加载器部分是否相关。预先感谢
I'm not sure if the "missing class loader part" is related though. Thanks in advance

EDIT EDIT
事实证明，这是Android Studio展示，否则除非您更新Google Play服务错误，否则该错误将不会运行，该错误使用API版本21（Android 5.0）解决了该问题。
As it turns out it is just another way Android studio manifest the won't run unless you update the Google Play Service bug, where using API version 21 (Android 5.0) solves the issue. Will need to do on device testing tho
推荐答案
如果本机配置与JavaScript配置不匹配或无法执行，则会出现此问题初始化。调试此问题的技巧之一是连接电缆，并使用DDMS / logcat查看输出。正常情况下，Google会打印出错误。
This problem occurs if the native configuration doesn't match the JavaScript configuration or failed to initialize. One of the tricks to debugging this is connecting a cable and using DDMS/logcat to look at the output. Google usually prints out an error when things don't work correctly.
请注意，您使用的 AIza __________________________________ 值必须是3个不同的值。一个用于本地Android应用程序，一个用于本地iOS应用程序，最后一个用于网络。
Notice that the AIza__________________________________ values you used must be 3 different values. One for a native Android app, one for a native iOS app and the last one for the web.
